Eimeria Patents (Class 424/267.1)
  • Patent number: 8257714
    Abstract: The present invention provides compositions and methods for the prevention and treatment of primary and metastatic neoplastic diseases and infectious diseases, for stimulating an immune response in a subject, and for use as an alternative to interleukin-12 (IL-12) treatment. In particular, the present invention provides Apicomplexa-related proteins (ARPs) that have immune stimulatory activity and thus have uses in the treatment and prevention of cancer and infectious diseases and in immune modulation. Compositions comprising an ARP are provided. Methods of use of an ARP for the prevention and/or treatment of cancer and/or infectious diseases, for use as an alternative to interleukin-12 (IL-12) treatment, and for eliciting an immune response in a subject, are also provided.

  • Patent number: 8110188
    Abstract: The invention refers to anticoccidial compositions consisting mainly of yolk immunoglobulins derived from eggs of hens immunized with one or more Eimeria species. The invention refers also to the use of said anticoccidial compositions for prevention or treatment of coccidiosis. The administration of immunoglobulins, both in liquid as well as in powder or pellet presentation, decreases mortality, lesions, oocysts counts and increases weight gain of receiving animals.

  • Patent number: 6998126
    Abstract: A method for obtaining an immunogenic strain useful for producing a vaccine against Coccidiosis comprises the cycle of infecting at least one first group of specific pathogen-free donor birds with oocysts from an Eimeria species. Blood is then collected from these donor birds, and is then used to infect a second group of specific pathogen-free birds. Oocysts are collected from the second group of birds. These oocysts are then multiplicated to complete the cycle. The cycle is then repeated using the multiplicated oocysts. After a total of about three cycles, a final antigen may be harvested and utilized as a source to generate oocysts for a vaccine.
